Question

I made a swing GUI using net beans, When I run the main project, the GUI is not showing up. But the output window shows the build successful.Run file is working ok. What might be wrong ? Thanks in advance..

Answer 1

Just guessing here, but do you actually create an instance of the GUI and then set it visible somewhere in a method, for example, your main() method?

For example

MyGuiClass app = new MyGuiClass();
app.setVisible(true);
